IC Programming 17MB18 has two programmable ICs, UOCIII (IC203) and 29XX800 (IC102, having the PW1306 (IC100) codes). 29XX800 (IC102) will be programmed before the TV production and will be mounted as programmed. On the other hand, software update can be needed after production so the programming instructions is given also for this IC in related chapter UOC III Programming Step 1: Entering to ISP Mode 1. Press Power On and turn on the TV. 2. Press Remote Controls (RC) Menu (M) and buttons respectively. 3. The following menu will displayed on the screen. GTV EurAsia TVSub Press RCs buttons respectively.( ISP Mode 0 line will be displayed on the screen.) 5. Press RCs Volume + button and set UOC to ISP mode..( ISP Mode 1 line will be displayed on the screen.) Step 2: Loading the Code 1- Connect the 5 pin cable of the programming board to PL203 of the 17MB18 mainboard. Connect the programming board to the computer in which WISP program is loaded via Paralel Port. 2- Run WISP program. As it is seen in figure1 change Delay time value to 5 ms. 3- Under Settings Menu, set the I2C configurations as it is seen in figure2; press Confirm and close this window. (Note: Once the above settings are done, there is no need to do them again each time loading the UOC code.) 4- Click Enter ISP Mode button and then click Send button. In the white display area with ISP status heading, ISP mode... Ready will be displayed. (Unless you do not see this warning, check the cable connections and the settings described above.)

For the TV production, pre-programmed 29XX800 will be mounted on the board. 1- Copy flasher.hex and romcode.hex to X:\XXX\ QTV_TVK2_V_021\Project\PW13XX_QTV directory. 2- Connect programmer board 4-pin cable to PL100 on 17MB Connect programmer board serial port cable to PC COM Port1. 4- Close jumper PL Execute FlashUpgrader.exe in C:\XXX\ QTV_TVK2_V_021\bin\ directory. 6- Press Choose and select romcode.inf from C:\XXX\ QTV_TVK2_V_021\Project\PW13XX_QTV directory. 7- Press Flash 8- Power on the board. Observe the sliding bar on the main menu showing that flasher.hex and then romcode.hex are being downloaded to the IC on 17MB18 main board. 9- Power off the board when the download operation is over. 10- Open jumper PL Power On the board. Press Remote Controls (RC) Menu (M) and buttons respectively. 12- By using RIGHT and LEFT buttons of the RC, select Service Submenu By using DOWN button of the RC highlight Init NVM. Press RIGHT button of the RC and initialize the PixelWorks side. 14- Turn Off and On the TV. 15- Depanding the size of the Panel(15, 17, 20 ) the screen may be full white and no picture is observed. If screen is full white: For 15 TV, Press Remote Controls (RC) Menu (M) and buttons and then 0 respectively. For 17 TV, Press Remote Controls (RC) Menu (M) and buttons and then 2 respectively. For 20 TV, Press Remote Controls (RC) Menu (M) and buttons and then 1 respectively.

9 3. SYSTEM BUILDING BLOCKS 17MB18 chassis main blocks are as follows: Analog Front End : UOCIII (Microcontroller + Video Proccessor + Sound Proccessor + IF), CTI, Tuner, SAW filters, Audio Amp., DAC Back End : PW1306(Microcontroller, Scaler, OSD, Keyboard/IR Interface) Side Board(s) : Keyboards, IR/LED Boards, TTL Panel Interface Cards, VCbCr Input Board (Optional) 3.1. Analog Front End 17MB18 Main Board consists of two major blocks. The first block is analog front-end and this block is handled by UOCIII chip that is highly multifunctional. This IC does demodulation of Video & Audio from Tuner IF, CVBS, Audio, RGB, SVHS input selection and processing. It has an audio processor that supports equalizer or tone control, volume control, AVL, surround effect etc and supplies amplifier, headphone and CVBS & audio line outputs. It handles video processing such as colour standard detection and demodulation, picture alignment (brightness, contrast, colour etc.). The IC also does teletext decoding with 10 pages text memory. After video processing, the processed video is applied to PW1306 chip in RGB format. The TV Tuner is an asymmetrical IF output type and is PLL controlled. For multistandard reception, a switchable SAW filter is used as the sound filter and it is controlled by SAW_SW output from UOC. After the SAW filter block, IF signal is applied to UOC IF inputs (VIFIN[1,2] and SIF[1,2]). As UOCIII can handle all the audio processing, there is no need for additional audio processor solution on the board. UOC supports three Audio outputs. These outputs are assigned to Headphone, Speaker and Scart Audio line outputs. The board employs TDA7056A and TDA1308 to drive speaker and headphone outputs respectively. As another dedicated output for Audio Line out from jack is not possible in UOC, this line out signal is obtained by using I2S input DAC CS4335. UOCIII I2S output is converted to anolog signal by DAC CS Tuner As the thickness of the TV set has a limit, a horizontal mounted tuner with longer connector is used in the product. The tuning is available through the digitally controlled I 2 C bus (PLL). Below you will find info on the Asymmetrical Tuner in use. General description: The tuner meets a wide range of applications. It is a combined VHF, UHF tuner suitable for CCIR systems B/G, H, L, L, I and I. The low IF output impedance drives a wide variety of SAW filters with sufficient suppression of triple transient.

Supported standards are B/G, D/K, I, L/L Back End The Back End section is handled by PW1306 chip. This IC has built in ADC s for RGB and SOY support. The RGB input can handle standard interlaced RGB output from UOC, PC VGA RGB input. As only 1 set of ADC is present in PW1306 these sources should be multiplexed. All the multiplexing operations are controlled by PW1306 via YUV_TV_SW (58) and VGA_TV_SW (57) signals.

This digital output is intended to interface to TTL compatible display devices. As PW1306 does not have integrated LVDS transmitter, 24 bit (even part of RGB) video output and TTL control signals from PW1306 are also inputted to DS90C385 LVDS IC to produce single pixel LVDS output for LVDS compatible LCDs. Backlight control is also possible via PW1306 Porta7 pin (PWMOUT, PL176-10), that is a variable duty-cycle pulse generator output TFT TV Service Manual 19/11/2003
